HT12D Description

The 212 decoders are a series of CMOS LSIs for remote control system applications. They are paired with Holtek¢s 212 series of encoders (refer to the encoder/decoder cross reference table). For proper operation, a pair of encoder/decoder with the same number of addresses and data format should be chosen.

HT12D Key Features

  • Operating voltage: 2.4V~12V
  • Low power and high noise immunity CMOS
  • Low standby current
  • Capable of decoding 12 bits of information
  • Binary address setting
